A patient's anterior fixed partial denture has become loose. What is the appropriate first next step?

  1. Take an alginate impression for diagnostic models, to assess the situation before deciding on re-cementation versus remake
  2. Immediately remake the prosthesis without further assessment
  3. Re-cement the prosthesis with the strongest available permanent cement immediately, with no further evaluation
  4. Extract the abutment teeth
Show answer and explanation

Correct answer: A. Take an alginate impression for diagnostic models, to assess the situation before deciding on re-cementation versus remake

When a fixed prosthesis becomes loose, taking a diagnostic impression (e.g., alginate for study models) allows proper assessment of the situation — checking for abutment tooth integrity, caries, fit issues, or other underlying problems — before deciding whether re-cementation, repair, or a full remake is the appropriate next step.
